SAMPLING-GAGE.

Patented June 16, 191-1.

Application filed October 28, 1912. Serial No. 728,231.

of the liquid is generally concealed from the exterior, such as barrels, casks, hogsheads, the gasolene tanksof automobiles, and like inclosures, and has for one of its objects to improve the construction and increase the efliciency and utility of devices of this character.

Another object of the invention is to provide a simply constructed device of this character whereby the depth of a liquid maybe accurately determined, or a sample of the liquid removed for inspection or testing. I

Another object of the invention is to devise a simply constructed device whereby a portion of the contents of a receptacle may be extracted from any part of the vessel and at any depth.

With these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims and in the drawings illustrating the preferred embodiment of the invention.

Figure 1 is a side elevation of the improved device. Fig. 2 is an enlarged longitudinal sectional elevation. Fig. 3 is a transverse section on the line 33 of Fig, 2.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the same reference characters.

The improved device may be of any required length and of any required size; and comprises a tubular body 10 preferably of glass or other transparent substance, and

' open at the lower end and with a plurality of recesses or notches 11 in the lower edge to enable the liquid'to freely flow into the tubular body when thelatter rests upon the bottom of the receptacle. A plug 12 is .vals are a inserted Within the body, preferably flush with the lower end, and provided with a relatively restricted vertical aperture 13 and with radial channels 27in the lower face and providing constant communication between the notches 11 and the aperture 13.. Located within the body and above the plug 13 is a loose float 14 of cork or like material.

At its upper end the tubular'body 10 is provided with a cap 15 preferably of metal and with a depending rim 16 inclosing the 'sides of the body and preferably threaded thereon. Rising from the cap 15 is areduced tubular extension 17 having a contracted opening 18 at the lower end communi'cating with the interior of the body. The extension 17 is preferably provided with sockets in the sides to receive the terwhereby the impleminals of a handle 19 ment may be readily handled and likewise suspended when not in use.

Located within the body 10 is a valve 20 having a suitable yieldable packing 28 whichis greater in diameter than the entrance 18 to the extension 17 and operates to close the latter when in elevated position,

ising from the "alve 20 is a stem 21 having a hood 22 which extends over the outer face of the extension 17 A spring 23 is located between the hood 22 and the shoulder formed'by the reduced entrance 18 of the extension, and operates to maintain the valve yieldably against the inner face of theportion of the cap 15 immediately surrounding the opening 18, and thus shuts off the flow of air through the opening 18 and into the extension. Suitable lateral vents 24 are formed in the extension 17 to permit the ingress and egress of the air.

Surrounding the body 10 at suitable interplurality of indicating rings 25 which are adjustable longitudinally upon the body and engage the latter with sufiicient friction to prevent them from movement thereon except when force is applied. By this means the rings are capable of adjustment-manuallv upon the tube and will be retained by friction in their adjusted position. The body 10 is also preferably provided with scale lines indicated at 26 to indicate the length in inches and fractions of inches or other dimensions to denote the length of the body and likewise to denote the depth of the" liquid in the receptacle with which the device is employed 'With a device thus constructed, it will be obvious that by lowering the-body into the liquid through the usual filling aperture or bung-hole until the bottom edge rests upon the bottom of the receptacle, and without actuating the push hood 22, that the pressure of air within the tube will prevent the liquid from rising therein.

When the tube is properly located in the receptacle pressure is applied downwardly upon the push member 22 to open the valve 20 and thus permit the air in the body to escape through the vents 24 and permitting the. atmospheric pressure to cause the liquid to flow through the recesses 11 and aperture 13 in the body, displacing-the float l t and causing the latter to rise with the liquid. The liquid will continue to rise in the body until it is level with the liquid in thereceptacle. The push member 22 is then released and the body withdrawn from the receptacle, the atmospheric pressure operating to maintain the liquid within the body. The operator can then observe the position of the float 14 through the transparent body and note its position relative to the scale 26, or adjust one of the rings 25 until it comes opposite the lower line of the float where it will remain, as above stated, by its friction. If it is not desired to retain the sample of liquid within the tubular body 10 the lower end of the body is inserted for a distance within the bung-hole or the filling cavity of the receptacle and the push member 22 depressed to permit air to enter it through the vents 24 and thus cause the liquid within the tubular member to flow back into the receptacle through the opening 13. By this means the depth of the liquid within the receptacle may be accurately ascertained.

If it is desired to retain the quantity of liquid which is contained within the body the lower end of the latter is placed over another smaller receptacle and downward pressure applied to the member 22 and the liquid contained in the body will'be discharged and retained for future use or testing. By this simple means samples of the liquid contained in the receptacle may be removed for testing or inspection as will be obvious.

By employing the improved implement a sample of liquid in a receptacle at any point therein may be removed for inspection or testing by disposing the lower end of the body at the point where the sample is to be taken and pressure applied to the member 22 when the liquid level with the bottom of the body only will flow upwardly into the body, leaving the remainder in the receptacle undisturbed. It will thus be obvious that a simply constructed device is produced which may be inexpensively manufactured of any required size and of any suitable material.

Having thus described the invention, what I claim is:

1. A combined depth and sampling gage comprising a tubular body having a reduced tubular extension at one end with a vent in the reduced extension and with an opening providing communication between the extension and the body, a valve closing the opening between the extension and the body,

a hood engaging over said extension and havin vertical side walls slidable over the extension and guided thereby, a stem con necting said valve and hood, and a spring bearing between said hood and the bottom of the extension and maintaining said valve yieldably closed.

2. A combined depthand sampling gage comprising a tubular body having a reduced tubular extension at one end with a vent in the reduced extension andwith an opening providing communication between the extension and the body, a valve closing the opening, a head engaging said tubular extension, a stem connecting said valve and head, and a spring bearing between said head and the bottom of the extension and maintaining said valve yieldably closed.

In testimony whereof I aflix my signature in presence of two witnesses.
